List of dog breeds

Dogs have been selectively bred for thousands of years, sometimes by inbreeding dogs from the same ancestral lines, sometimes by mixing dogs from very different lines. The process continues today, resulting in a wide variety of dog breeds and types. Dogs are the only animal with such a wide variation of breeds, it is unknown why their genetics differ so dramatically compared to the majority of animals.

The following list uses a wide interpretation of "breed". Breeds listed here may be traditional breeds with long histories as registered breeds, rare breeds with their own registries, or new breeds that may still be under development. Please see individual articles for more information. For breeds categorized by national origin, refer to the list of dog breeds by country.

This list only includes each dog once, using the most commonly used name.
